Grundfos Control MPC is a control cabinet with a CU 351 controller that permits monitoring and control of up to six identical pumps connected in parallel. It comes with everything needed to get started, and contains software optimised for your particular application. Control MPC will minimise energy consumption and cut energy costs straight out of the box. With application-optimised software, you have complete control over the pumps in your system. Features such as automatic cascade control ensure the highest possible system energy efficiency.
As the only system on the market, Control MPC knows exactly which – and how many – pumps to control, and will optimise performance and minimise energy consumption based on user-supplied pump curve data.
With Control MPC, there are no communication barriers. You are free to choose between a wide range of operating languages, and Control MPC supports communication with monitoring equipment or other external units via a number of different fieldbus protocols:
Grundfos Booster that you connect to a Modbus network. Note that the Hydro MPC and Control MPC are available in two variants: with a CU 351 or a CU 352 control unit. They have different CIM/CIU connections, as described below. CIM solution The Communication Interface Module (CIM) is an add-on. CU 351 is a flexible control unit for controlling and monitoring of up to six identical pumps + a pilot pump. CU 351 serves as the controller for Grundfos Hydro MPC booster sets and Control MPC systems. The Grundfos ALPHA2 circulator with AUTOADAPT are predicated on: 65-years of hydronic experience of how pumps work in countless applications and operating environments; 15+ years of ECM motor experience in the market; ALPHA2 materials and design resist blockage from magnetite and iron oxide particles found in closed hydronic systems.
- Ethernet (VNC server is standard in Control MPC)
- PROFIBUS via CIU modules
- LON via CIU modules
- Modbus via CIU modules
- GSM and GPRS via CIU modules
- PLC via IO 351B modules
The Control MPC is designed and built to the same exacting quality standards as all other Grundfos products. Features such as standby pump allocation, forced pump changeover and dry-running protection help to increase your system reliability and decrease downtime and costly maintenance. All it takes for you to start enjoying these Control MPC benefits is to follow the simple installation wizard, which helps you set the desired parameters in the correct sequence.

Overview
The CU 301 is a control and communication unit developed for SQE well pumps used in constant-pressure applications.
Applications:
The CU 301 control unit provides:
- Full control of the SQE pump.
- Two-way communication with the pump.
- Simple pressure adjustments.
- Alarm indication (LED) when service is needed.
- Configuration with R100 remote control.
- Configuration with Grundfos GO Remote.
The CU 301 communicates with the pump via mainsborne signalling (Power Line Communication),meaning that no extra cables are required between the CU 301 and the pump.
Features & Benefits:
CU 301 control can detect:
- No contact to pump
- Overvoltage
- Under voltage
- Speed reduction
- Over temperature
- Overload
- Sensor defective.
The CU 301 incorporates:
- External signal input for pressure sensor
- Connection to an operating relay for indication of pump operation.
Other Features:
1. Pump running indicator
- System pressure setting
- System ON/OFF
- Button lock indicator
- Dry-running indicator
Optional R100 remote control
Wireless infrared remote control of the CU 301 is possible by means of the R100. Using the R100, it is possible to monitor and change the operating parameters of the pump.
Optional Grundfos GO Remote
Benefits
- Complete solution
- Easy set-up
- Built-in protection features
